[DISCUSS] Drop Java 6 support in 0.8
Java 6 support ended quite a while ago. Trying to support it gets in the
way of using libraries which may work with Java 7 only (Netty for example
in TEZ-2450). I think we should move Tez 0.8 to work with Java 7 as the
minimum version. Thoughts ?
Thanks

@Mohammad, Hadoop is dropping support for 1.6 from 2.7.0 onwards. I am guessing other ecosystem projects will soon follow suit.

Doing a quick search - Hadoop 2.2 and beyond seem to work with Java 7 (
http://wiki.apache.org/hadoop/HadoopJavaVersions). Vendors have been
shipping with Java 7 support for quite some time. That should take care of
allowing Tez with Hadoop 2.2 libraries to work on older clusters, unless
the users are still on Java 6 - in which case 0.8.0 would not be supported.
In terms of Hadoop versions supported, I think it'll be useful to have a
separate discussion on which versions we want to support. There's been a
fair amount of grief from ATS integration, builds breaking against older
versions, etc.

Re: [DISCUSS] Drop Java 6 support in 0.8

To clarify, my main point was that to run Tez 0.8 with java7 features would need the hadoop cluster to be running with java7 ( or atleast support a way for the YARN containers to use a different java version i.e java7 ).
Users on older versions of hadoop running java6 would likely not be able to run a future version of Tez ( even though Tez would be sort-of “compatible" with that older hadoop version except for the java version issue ).
I still think it is good idea to move to java 7 but it does mean that we are going to be dropping support for certain users ( hopefully most of them are not running with java6 ).

To clarify, my main point was that to run Tez 0.8 with java7 features would need the hadoop cluster to be running with java7 ( or atleast support a way for the YARN containers to use a different java version i.e java7 ).
Users on older versions of hadoop running java6 would likely not be able to run a future version of Tez ( even though Tez would be sort-of “compatible" with that older hadoop version except for the java version issue ).
I still think it is good idea to move to java 7 but it does mean that we are going to be dropping support for certain users ( hopefully most of them are not running with java6 ).

Hi Hitesh,
I think you took Prakash¹s question to be a statement.
What is being suggested here is not "we drop support for all older hadoop
versions² - but is really ³switch to the same version² as every downstream
project.
Let me repeat - we are *NOT* dropping support for older hadoop versions,
we are upping the minimum JDK version you can run the whole ecosystem on.
For that measure, the Upstream sourceVersions don¹t matter, what matters
are downstream sourceVersions of tools which use Tez.
Cheers,
Gopal

Re: [DISCUSS] Drop Java 6 support in 0.8
Posted by Gopal Vijayaraghavan <go...@apache.org>.
Hi Hitesh,
I think you took Prakash¹s question to be a statement.
What is being suggested here is not "we drop support for all older hadoop
versions² - but is really ³switch to the same version² as every downstream
project.
Let me repeat - we are *NOT* dropping support for older hadoop versions,
we are upping the minimum JDK version you can run the whole ecosystem on.
For that measure, the Upstream sourceVersions don¹t matter, what matters
are downstream sourceVersions of tools which use Tez.
Cheers,
Gopal

Excellent point @Prakash. I would probably change my vote to a -0 on that point itself.
It might be easier to say drop java6 support but harder to say we drop support for all older hadoop versions that need/support java 6.

Excellent point @Prakash. I would probably change my vote to a -0 on that point itself.
It might be easier to say drop java6 support but harder to say we drop support for all older hadoop versions that need/support java 6.

Hi,
+1 here.
PIG & Hive are JDK7 targetVersions.
https://github.com/apache/pig/blob/trunk/build.xml#L64
https://github.com/apache/hive/blob/master/pom.xml#L616
Flink & Spark have JDK8 code in them via activation.
>From earlier mails, I remember seeing only JDK7 bugs reported for Tez so

Datameer also recommends JDK 1.7, IBM Big Insights uses JDK 1.7. Hadapt
had /opt/teradata/jvm64/jdk7.
HDInsight uses JDK7 Zulu (AFAIK, there¹s also a 1.8 Zulu available on A1).
So I feel like we¹re well past the chasm here.

https://github.com/apache/hive/blob/master/pom.xml#L616

Datameer also recommends JDK 1.7, IBM Big Insights uses JDK 1.7. Hadapt
had /opt/teradata/jvm64/jdk7.
HDInsight uses JDK7 Zulu (AFAIK, there¹s also a 1.8 Zulu available on A1).
So I feel like we¹re well past the chasm here.

Java 6 support ended quite a while ago. Trying to support it gets in the way of using libraries which may work with Java 7 only (Netty for example in TEZ-2450). I think we should move Tez 0.8 to work with Java 7 as the minimum version. Thoughts ?
